Definitions
- the present invention relates to a dual heating or cooling system.
- the present invention relates to a system which, depending upon the electric volt- age applied to the system, and consequently upon an electric current flowing through the system, allows a transfer of heat from one side of the system to the other side thereof.
- a voltage is applied to the system, heat is trans- ferred from one side of the system to the other, thereby creating a temperature gradient caused by charge carriers in the material of a thermocouple diffusing from the elevated temperature side of the thermocouple to the reduced tempera- ture side thereof.
- the present invention also relates to a radiation-emitting apparatus, as for exam- ple a body irradiation apparatus, non-restricting examples of which are tanning beds, tanning booths or other apparatus irradiating useful radiation onto a subject as, for example, a human or animal body, said apparatus comprising a dual heat- ing or cooling system configured to transfer heat from a heat-emitting appliance, e.g. a heat source, of the radiation-emitting apparatus to a heat sink providable as a component of the radiation-emitting apparatus.
- a heat-emitting appliance e.g. a heat source
- the present invention also relates to the use of a dual heating or cooling system configured to effect heating or cooling to areas or parts of a radiation-emitting apparatus where heating or cooling is required or desired.
- the invention relates to a method of heating or cooling areas or parts of a radiation-emitting apparatus during a radiation-emitting operation thereof.
- a Peltier device also called“Peltier cooler” or“Thermo-Electric Cooler” (TEC) is a solid state active heat pump in a basically sandwich-type shape (see Figure 1 (https://en.wikipedia.org/wiki/thermoelectric_cooling)): Two or more cuboids made of two different semiconductor materials, one of them p-type, the other one n-type (as non-restricting examples: bismuth telluride; silicon germanium), are sandwiched, thermally in parallel to each other and in pairs connected electrically in series by conductive metal bridges, between two non-conducting plates (as non-restricting example: made of alumina ceramics).
- TEC Thermo-Electric Cooler
- Cooling or heating by means of a Peltier device is considered favorable in view of the easy controllability by changing the input voltage or current, in view of the exactness of the temperature control within fractions of degrees, in view of the high shape flexibility of Peltier devices (which may be configured in any shape and size required for a specific application) and in view of the Peltier device's reliability (no moving parts, maintenance rarely required).
- Radiation-emitting apparatus as for example body irradiation apparatus, non-re- stricting examples of which are tanning beds or tanning booths or other apparatus irradiating useful radiation onto a subject as, for example, a human or animal body, are operated by providing a place for a subject as for example a person wanting to receive a radiation treatment in a standing position in an irradiation treatment booth (e. g. in a tanning booth) or in a recumbent position on an irradi- ation treatment bed (e. g.
- the term“radiation-emitting apparatus” or“radiation-emitting device” is under- stood to mean apparatus and devices configured to emit radiation of one wave- length of the actinic spectrum, or radiation of a plurality of wavelengths or of a wavelength band of the actinic spectrum comprising more than one, several or plural wavelengths onto the body, or to parts of a body, of a subject, for example (but not restricting to) a human or an animal exposed to such radiation.
- the type of radiation irradiated by the radiation-emitting apparatus is not re- stricted in the context of the present invention (in the same way as in a consider- ation of relevant prior art) and may be, for example and not restricting, UV radia- tion (UV-A radiation and/or UV-B radiation and or UC-C radiation), visible light radiation, IR radiation (near IR radiation, far IR radiation).
- the radiation-emitting apparatus may comprise, as the radiation-emitting source, high-pressure lamps, medium pressure lamps, low-pressure lamps, and/or LEDs in the form of single LEDs or LED arrays (i. e. LEDs configured to emit radiation of one or two or several wavelengths, wavelength ranges or wavelength bands of the UV, visible and IR ranges), or may comprise combinations of the afore- mentioned radiation-emitting sources.
- the purpose of irradiating radiation onto the subject's body is not restricted.
- the purpose may be a medical purpose or a non-medical purpose, for example a cosmetic purpose or a wellness purpose.
- Non-restricting examples are radiation-emitting apparatus or devices for tanning the subject's body, for initiating the Vitamin D3 generation in the subject's body, for initiating the collagen, keratin and hyaluronic acid generation in the skin of the subject's body, for effecting a skin treatment, including a treatment of curing one disease or several diseases of the skin or for directly curing one or several diseases hav- ing the same etiology or having different etiologies of the subject's body, for effecting a photo-dynamic therapy for treating one specific disease or certain dis- eases of the subject's body; etc.
- the above enumerative description is not ex- haustive and does not restrict the invention.
- the treatment booth e. g. the tanning booth
- the treatment bed e. g. the tanning bed
- body irradiating apparatus were equipped with a heating device allowing to achieve a comfortable temperature of the space or surface for accommodating the subject or person to be irradiated.
- Such a heating device for example a heat- ing fan assembly, not only required a more complicated, and in many cases also a considerably larger, space-filling, configuration of the irradiation device, but also had to be supplied with large amounts of energy for the blowing-heating step.
- the radiation sources in the form of heat.
- heat emitted by the radiation sources has to be dissipated in order to create a comfortable climate for the subject or person receiving the radiation treatment.
- the excess heat is removed from the radiation space or radiation-exposed surface(s) by one or more suitable temperature-conditioning (e. g. air-conditioning) devices option- ally provided with one or more suitable blower(s). While the heat dissipated into the environment can create a comfortable climate to the user of the irradiation device, the heat is discarded and cannot be used expediently.
- the steps of heating and cool- ing the treatment space or treatment surface or parts of a radiation-emitting ap- paratus be effected by the same system allowing a dual heating or cooling mode operation dependent upon the physical operation conditions thereof.
- a dual heating or cooling system be provided which is small enough to be installed in narrow spaces and not as voluminous as conventional heat-conditioning (heating or cooling) devices, thereby granting construction designers more freedom in positioning a required heating or cooling system.
- a temperature of the radiation treatment space or surface comfortable for the user of a body irradiation apparatus be adjusted before the start of the irradiation procedure with a straight- forward and energy efficient heating installation.

- the desired temperature control and temperature adjustment can be effected more promptly and more ex- actly than in customary systems.

- the dual heating or cooling system provided is small enough to be installed in narrow spaces and is not as voluminous as conventional heat- conditioning (heating or cooling) devices. Hence, construction designers have more freedom in positioning a required heating or cooling system.
- the temperature of the radiation treat- ment space or surface can be adjusted to be comfortable for the user of the de- vice before the start of the irradiation procedure with a straightforward and energy efficient installation. Even more, an excess heat generated by the irradiation sources in the course of the irradiation procedure is dissipated easily by an effi- cient cooling device.
- the advantages of the invention are apparently that several disadvantages of the temperature management of radiation sources in the treatment space or on the treatment surface of radiation- emitting devices can be remedied.
- a tempera- ture of the radiation space or surface comfortable for the user of a body irradiation apparatus can be adjusted before the start of the irradiation procedure with a straightforward and energy efficient heating installation.
- an easy and efficient dissipation of excess heat generated by the radiation sources in the course of the irradiation procedure could be achieved by using the efficient cool- ing mode of the dual heating or cooling system of the invention.
